HAY BAKE AND COCKER.

Specification of Letters Patent.

Patented June 8, 1909.

Application filed July 25, 1907. Serial No. 385,497.

To all whom 'it may concern:

Be it known that I, WILBERT C. TRUS- sELL, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Hay Rakes and Cookers, of which the following is a specification.

This invention relates to a machine for raking grass, hay or similar material from a field whereon it is spread, and gathering the same` into a compact cock which can be dep'osited again upon the field at any point desire The object of the invention is to make a practical machine for this purpose which will be as simple in construction and as economical to build and operate as possible, and which will eliminate necessity for manual labor on the part of the operator, thereby insuring the maximum capacity and efficiency of the machine.

In carrying out my invention I have devised a machine of which the preferred embodiment is illustrated in the accompanying drawings, in which,-

Figure 1 represents a side elevation of the machine, showing all the parts except the nearest supporting wheel which has been removed for increased clearness. Fig. 2 represents a plan view of the machine. Fig. 3 represents a rear elevation. Fig. 4 represents a sectional rear elevation, showing the parts in front of the line 4 4 of Fig. l. Fig. 5 represents a fragmentary elevation of the rear part of the machine, showing the cock former raised and opened for the purpose of dumping its contents. Fig.6 represents a fragmentary detail elevation of one of the rake tines and the manner of mounting the same. Fig. 7 represents a front elevation of the parts shown in Fig. 6. Fig. 8 represents a sectional elevation of a tine used in a different part of the rake. Fig. 9 represents an elevation and diagrammatic view of the hay packer, the means for operating the same, and the manner in which it moves. Fig. 10 represents a sectional view of a form of clutch capable of being used in this machine for causing the supporting wheels to drive the operating parts. Fig. 11 represents a view similar to Fig. 10, showing the parts of the clutch in a different position, being taken on line 11-11 of Fig. 12. Fig. 12 represents a sectional detail view of one of the supporting wheels and the clutch, being taken on line 12-12 of Fig. 11.

The same reference characters indicate the same parts in all the figures.

The essential parts of the machine are similar to those illustrated and described in my prior patent granted February 19, 1907, and numbered 845,018, consisting of a rake 1 having a depressed central portion to form a discharge outlet, a cock former 2, and chut-e or guide 3 for leading the hay discharged from the rake rearward to the mouth of the former 2. The rake is formed on a frame consisting of a laterally extending bar 4 to which near the ends rare connected the forwardly inclined bars 5 andv to which the longer rake tines 7 are connected and from the central portion of which is hung the bar 8 to form the depression in the rake permitting rearward discharge of the hay. The bar 4 extends continuously across the machine in order to give the necessary strength, and is raised at its central part so as to provide a large assage for the collected hay. In the ends of the transverse forward frame are contained axles 9 and 10 on which the main supporting wheels 11 and 12 are secured. The rear portion which carries the cock -former and chute consists of a separate frame having a bottom platform 13 and uprights 1 4 and 1'5 connected by a bow 16. The front portion of the rear frame is pivotally connected by a transverse rod 17 with the depending portion of the forward frame. This rod carries the central shorter tines 19 of the rake.

In the present form of the invention the cock former is made in two parts which, when brought together, form a somewhat dome-sha ed receptacle open at one end and normally `eld in a horizontal position with its o en end forward and directly in rear of the c ute 3. The division plane between the two parts of the former passes approximately through the axis and is horizontal when the former is in normal position. The upper 'portion 22 of the former is provided with trunnions 23 which arecontained in bearings in the uprights 14 and. 15 and to the ends' of which are connected crank arms 24 and 25 by which the former may be rotated and by which the lower or separable part 26 of the former is carried. As seen in Figs. 1 and 3, the support for tlvl lower portion of the former is a bow 27 oi which the ends are secured to the arms 24 and 25 and which is united to the part 26 by a bottom. strap 2S and lateral braces 29 and 30. ligidly connected with the ends of the bow 27 are gears 31 which mesh with pinions 32 mounted. concentrically with the trunnions 23 but secured fxedly to the uprights 14 and 15 so as to be incapable of any rotation whatever. On account of this arrangement of gearing, the parts of the former are caused to separate whenever the former is tilted from a horizontal to an upright position. Swinging of the arms 24 and 25 to the left, as seen in Fig. 1, simply turns the upper section of the former into a vertical position, but the gearing causes the lower section to have a Vfurther movement in the same direction. As the gears 31 are caused to roll about the pinions 32 by the movement of the arms which carry them, they are caused also to turn on their own axes, thereby giving a planetary motion to the lower section 26 and causing it to travel approximately twice as far as the upper section. Thereby the same motion which causes the former to be turned up as a whole also causes the rear section to be separated from the upper or forward section so as to offer no obstruction to the escape of the hay contained therein. The open or dumping position of the former is shown in Fig. 5. In order to balance the weight of the lower section of the former, I provide springs 33 which are connected to the arms 24 and 25, and also to fixed abutments. The direction of the springs is such that when the former is closed and in receiving position, they exert their force nearly through the pivotal axis of the former and produce practically no tendency to turn, but act with an increasing lever arm as the turning movement progresses.

In order to relieve the operator of all unnecessary labor, and to render the machine as nearly automatic as possible, I provide connections which cause the movement of the machine itself to tip the former and dump the cock so that none of this work need be done manually. To this end I mount a crank shaft 34 having crank arms 35 directly forward of the arms 24 and 25, while to the latter I pivot connecting rods 36. These rods are formed at their forward ends with hooks 37 adapted to hook over and catch the cranks 35, so that whenever they are so engaged and the crank shaft is rotated, the arms 24 and 25 will be automatically drawn forward and the cock former dumped.

rfhe crank shaft is driven by the supporting wheel axles through sprockets 38 and 39 and chains L10 so as to turn continuously as long as the machine is in motion, whenever certain clutches, to be presently described, are thrown into gear. The connecting rods, however, are normally held out of the path of the cranks 35 by means of a hanger 41 which extends across between the connecting rods over the forward end of the former when the latter is in normal position, and is supported by such forward end. The hanger is disengaged Yfrom the cock former so as to allow the connecting rods to he engaged with the cranks by the manual action of the operator who gives a preliminary movement to the cock 'former which is linst sullicient to depress its lower end and move forward the connecting rods and hanger enough to allow the latter to dro J.

The operator being seated in the drivers seat 4t2, has near at hand a lever 4?) which is secured to a rock shaft 44 mounted in hearings 45 on a forwardly projecting portion `to of the front frame. From the ends of this rock shaft rise arms 4t? to which are pivoted the ends of links 4S connected at their further ends with the arms 24 and 25. As will be readily understood., a forward swinging movement of the lever will tilt the cock former and at the same time move the connecting rods and hanger forward. As soon as the hanger has cleared the end of the former, the hooks 37 drop into the path of the cranks 35 and are engaged by the latter as soon as they approach. After this engagement takes place, the continued movement of the cranks swings the parts of the former through their full arc and then returns them to normal position. The last part of the return movement of the vformer is caused by its own weight, which is so distributed that the center of gravity comes in rear of the pivot when nearing horizontal position. Consequently, after the forward end of the cocker has risen under the hanger L'11, its weight causes it to return fully into normal position, and in doing so, to lift the hooks from the cranks. After arriving in its normal position, the cocker is locked there by a latch L19 which is urged h v a spring 5t) to catch over a pin 51 carried by the cock former (see Figs. 1 and 3). This latch is connected through a link 52 with an arm 5:; on a sleeve 54' tlig. 2), said sleeve having a second arm 55 connected by a link 5G with a trigger 57 carried by the lever 13. Before operating the lever, the driver first moves the trigger toward the lever handle so as to turn the sleeve and release the latch from the pin 51. The cocker is then unlocked and subsequent forward movement of the lever is enabled to turn it through the preliminary movement -for the purpose above described.

It is desirable not to have the rock shaft 34 continuously in motion, and for the purpose of causing this rotation to take place when desired, I provide diseonnectihle clutches between. the supporting wheels and the sprockets 38. One of these clutches is shown in Figs. 10, 11 and 12. In these ligures 58 represents the hub of one of the main wheels on which is formed a clutch member 59 having internal gear teeth (it). '.l` he sprocket wheel 38 is mounted loosely on the aXle and carries connected to it by pins 61 a drum 62 which is located within the clutch member 59 and has notches in its periphery to receive dogs 63. Each of these dogs has a rounded end which fits into one of the notches and is pressed outward at its other end by a spring 64 so as to engage the teeth 60. Between the part 59 and ratchet wheel is a disk 65 having pins 66, one for each dog, which are so located as to be capable of en gaging protuberances 67 on the dogs and crowding them against the pressure of the springs out of engagement with the teeth. This disk is mounted on the hub of the sprocket with sufficient frictional resistance to stay wherever it is placed, and moves with the latter and with the drum 62. AIt has peripheral teeth 68 whereby it may be turned so as to disengage the dogs from the clutch teeth or to allow them to become engaged.

For the purpose of transferring the hay rearwardly, and packing it into the cocker, I provide packers 69. There may be one, two or more of these packers, as desired, but in the present embodiment of the machine I have shown two. These packers are in the form of forks having handles 70 pivoted by means of links 71 to the forward part of the front frame so that the front ends of these fork handles may-have a swinging movement. Intermediate their ends the packers are engaged by cranks 72 which are rotated by the movement of the machine, and cause the forks to travel in a circumferential orbit, such as shown in F ig. 9 by dotted lines. Each fork dips into the hay, forces it backward into the cocker, and then rises and moves forward again above the mass of hay. To accelerate the movement of the forks, I have formed the cranks 72 upon an intermediate rock shaft 73 contained between the ends of the rock shaft 84, which is divided so as to avoid interference with these cranks, and each section of which carries an internal gear 74. The secondary shaft 73 carries on its ends pinions 75 meshing with the internal gears, and is thereby turned at a much accelerated rate, as will be readily understood.

It is desirable to be able to tilt the forward frame so as to elevate the tines of the rake above the ground to avoid obstacles. To this end I have provided a lever 76 which is adapted to engage a rock shaft 77 mounted in brackets 78 which are secured to the upper part of the forward frame above the wheel axles. This rock shaft carries on its ends arms 79 which are connected by means of links 80 with the rear uprights 14 and 15. The connection between the lever 76, which is pivoted so as to turn loosely on the rock shaft and the arms, is made by a notched disk 81 secured to the shaft, which is engaged by a latch 82 on the lever and operated in the usual manner by a trigger 83.

When the latch is engaged with one of the notches and the lever 76 thrown forward or back, the arms 78 are moved out of line with the links 80 so as to shorten the distance between the rock shaft 77 and the rear part of 70 the frame. The rock shaft 77 is then moved backward and the rod 17 which pivotally connects the front and back frames, is moved forward and upward. The front frame is thus tipped, and its lower part raised so as to lift the rake tines above the ground. The space between the bars 4 and 8 of the front frame is sufficiently deep to allow the chute to move forward so that a considerable range of movement is permitted, whereby the tines may be elevated as high as necessary under conditions which permit the use of a horse rake. The tines may be held in this elevated position by a spring latch 84 engaging the notches of the disk 81, said latch being se- 85 cured to one ofthe brackets 78. A foot lever 85 is pivoted beside the latch and carries a pin 86 resting upon the same by which the latch may be disengaged whenever it is desired to lower the rake. When such. release is effected, the parts return to normal position by the weight of the displaced portions of the forward frame.

One of the improvements of the present invention consists in the manner in which the tines of the rake are mounted so as to be sufficiently stiff to collect the hay, and at the same time yielding enough to give way when striking a rigid obstacle to avoid breakage. The longer tines are carried by brackets 87 secured to the bars 5 and 6. The ends of these tines are doubled back and bent laterally, being passed into and then longitudinally through the bracket, as shown most clearly in Fig. 7. A spring 88 is coiled about the bracket and is engaged at one end with the tine and at the other with the under side of the bracket, tending to throw the lower end of the tine forward as far as permitted before the spring abuts against a portion of the bracket. A lip 89 on the end of the bracket prevents the spring from slipping off the end thereof.

The intermediate short tines 19 are carried by the bar 17 and are inclined sharply 115 forward. Each tine is engaged by a spring 90 which tends to project it forward, but allows it to be moved backward bodily whenever it strikes a rigid obstruction. Surrounding the bar 17 are springs 91 which bear 120 against the lower transverse bar 8 of the main frame and retain the rod 17 and tines in proper angular position.
